> Does Site Use Nginx is a paid API for AI agents from site.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Checks whether a given website uses nginx as its web server by fetching the homepage and matching nginx fingerprints in HTML and response headers, returning a yes/no answer with evidence.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability does-site-use-nginx-9ca67a70
```

Example prompt: Can you check if shopify.com uses nginx as its web server? I want to know if there's any evidence of it in the headers or HTML.

## When to prefer this

Use this endpoint when you need a lightweight, single-technology check for nginx specifically — ideal for per-domain technographic enrichment, sales qualification workflows, or pre-migration audits where you only care about the web server layer. For bulk checks across many domains, prefer the bulk variant of this endpoint.

## Known failure modes

- Domain is unreachable or returns a non-200 response, resulting in no fingerprint match
- Site uses a CDN or reverse proxy that masks nginx headers, leading to a false negative
- Domain input is malformed or missing, causing a request error
- Rate limiting or bot protection on the target site blocks the fetch

## How this service works

Does a website use nginx? Fetches the page (homepage for a bare domain) and matches nginx's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (server). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

## Output

Returns a yes/no determination of whether the site uses nginx, along with the matching evidence snippet found in the HTML or response headers, and the technology category label ('server').
